Web29 Dec 2024 · Cryptographic hash functions have wide range of applications. They can be used to store user passwords, which makes it possible to verify if password is correct without knowing the password. They are used to generate pseudorandom numbers, by applying hash function many times to some seed input. WebThe FNV1 hash comes in variants that return 32, 64, 128, 256, 512 and 1024 bit hashes. The FNV-1a algorithm is: hash = FNV_offset_basis for each octetOfData to be hashed hash = hash xor octetOfData hash = hash * FNV_prime return hash Where the constants FNV_offset_basis and FNV_prime depend on the return hash size you want:
